A state agency has released a virtual tour of Kentucky's energy history dating back to the 18th century.

The timeline features videos and pictures that allow viewers to explore Kentucky's historical energy events. It stretches from 1750 with the first discovery and use of coal to December 2014 when the first utility solar generating facility was approved for Mercer County.

The virtual tour was released by the Kentucky Department for Energy Development and Independence.

Viewers will see how national and federal actions have influenced energy development and the diversity and innovation that exist in Kentucky's energy landscape.

State officials say such projects support Gov. Steve Beshear's Energy Plan by helping to educate the public on energy issues. The timeline also provides a tool for students to explore and discover energy topics.
